TM 9-254 7-6  Inductor Identification. Although  not  used  as  much  as  resistors  and  capacitors,  inductors  are  used  generally  in  tuning  sections  of  electronic circuits  Inductors  may  be  fixed  or  variable  as  is  the  case  with  resistors  and  capacitors.    Figure  7-12  provides  several examples  and  indicates  the  color  code  used  for  marking  radio  frequency  (rf)  inductors.    Variable  inductors  will  usually have the size and voltage ratings marked on the side of the inductor.
